Abstract: An anti-inflammatory analgesic patch containing loxoprofen, crotamiton, solvent, skin permeation accelerator, water-soluble polymers and moisturizers. The patch allows for the loxoprofen to penetrate the skin.

Abstract: An external preparation containing tranilast which is excellent in the release of the active ingredient contained therein, achieves a high percutaneous absorption, fully ensures the effective drug concentration in the skin tissue and little irritates the skin This preparation is composed of an aqueous base containing as the active ingredient tranilast, its salt or a mixture thereof. The aqueous base contains a solubilizer for tranilast, a dispersant, an absorption aid, an adhesive and/or a shape retenting agent, and water. The active ingredient has been solubilized by the above-mentioned solubilizer and dispersed in the aqueous base by the above-mentioned dispersant.

Abstract: Compounds including 1-(biphenyl-4-yl)methyl-1H-1,2,4-triazoles and 1-(biphenyl-4-yl)methyl-4H-1,2,4-triazoles each having a (2,4-dioxopyrrolidine-5-ylidene)methyl or (2,4-dioxo-tetrahydrofiuran-5-ylidene)methyl group as the substituent at the 2′-position and salts thereof are lowly toxic and highly safe and are useful as an angiotensin II antagonist. Thus, these compounds can be used in medicines, which contain these compounds as an active ingredient.

Abstract: A lens system is constituted by a cemented lens made of anomalous dispersion glass for correcting the secondary spectrum of axial chromatic aberration, and a plastic lens having a temperature-compensating characteristic for compensating for defocusing upon change of the lens system with respect to temperature, thereby satisfactorily correcting color and compensating for temperature at the same time in a simple configuration. The imaging lens for image readout is constituted by eight sheets of lenses L.sub.1 to L.sub.8, in which the fourth lens L.sub.4 and the fifth lens L.sub.5 form a cemented lens made of anomalous dispersion glass, whereas the first lens L.sub.1 is a substantially powerless plastic lens having a temperature-compensating characteristic for compensating for defocusing upon change in the lens system with respect to temperature.

Abstract: Provided is a color-image-reading Gaussian lens for reading out color images, color originals, or negative or positive films, which is suitably used at a low magnification of -1/2.5.times. to -1/1.25.times., effectively corrects axial chromatic aberration in particular, and exhibits high performances in a wide wavelength range. A six-sheet Gaussian lens comprises, successively from an object side, two convex lenses, two concave lenses, and two convex lenses, while a stop is disposed between the two concave lenses. In particular, the following conditional expressions are satisfied:0.10<D.sub.5 /f<0.230.82<R.sub.5 /.vertline.R.sub.6 .vertline.<1.30.0012<.SIGMA.(.phi..sub.i .multidot..delta..theta..sub.i)<0.0045where .phi. is refracting power, and .delta..theta. is anomalous dispersion.

Abstract: A release controlled transdermal therapeutic system having excellent storage stability and capable of optionally controlling the release rate of drugs, comprising a rubbery adhesive, microcapsules comprising a water-soluble wall material and encapsulating drugs as core material, and a water-insoluble, rubber- and rubber solvent-insoluble, water absorbing resin powder, such as starch-polyacrylic acid salt copolymers, the microcapsules and the resin powder being dispersed in the rubbery adhesive.

Abstract: A fixed-focal-length lens system includes first and second lens groups arranged in order from front to rear. The first lens group consists of a plurality of lenses and has a negative refracting power and the second lens group consists of a plurality of lenses and has a positive refracting power. The fixed-focal-length lens system satisfies the following conditions0.58<.vertline.f.sub.1 /f.vertline.<0.95 (1)0.50<.vertline.f.sub.1 /f.sub.2 .vertline.<1.0 (2)1.6<Bf/f<2.9 (3)1.1<f.sub.2 /f<1.45 (4)wherein f represents the focal length of the fixed-focal-length lens system, f.sub.1 represents the focal length of the first lens group, f.sub.2 represents the focal length of the second lens group and Bf represents the back focus of the lens system.

Abstract: A zoom lens with a close-up lens has first to fifth lens groups arranged in this order from the object side. Each of the first, second and fifth lens groups has a positive power and each of the third and fourth lens groups has a negative power. The first to fifth lens groups are arranged so that the spaces between the second to fifth lens groups change when the zoom lens is zoomed from a shortest focal length to a longest focal length and at the same time the first lens group can be moved along the optical axis in response to change in the optical length between an object point and the first lens group so that the object side focal point of the first lens group coincides with the object point.

Abstract: This invention relates to a catalyst for the hydrotreating of heavy hydrocarbon oils, which catalyst comprises a dual structure including a porous core (1), made chiefly of alumina, which has micropores having an average size smaller than 170 angstrom and to which at least one active metal is applied, and a surface layer (2) comprised mainly of at least one clay mineral selected from the group consisting of sepiolite, halloysite, attapulgite, palygorskite, and asbestos. The active metal may be applied to the surface layer (2) as desired.

Abstract: Provided is a method for the preparation of alumina or silica-alumina catalyst carriers which comprises blending a precursor of alumina or silica-alumina carriers with polytetrafluoroethylene resin particles, warming the blend and subjecting the same to a compression and shearing operation in a blender, followed by drying and baking.

Abstract: A process for the production of hydrogenation catalysts is disclosed which is characterized by the use of citric acid or malic acid as a stabilizer in a specified amount with respect to Group VI metal salts which are used in combination with Group VIII metal salts to produce an impregnating solution. The solution is impregnated with alumina or silica-alumina and calcined to form a catalyst.
